SYRINGE.

Application filed May 13,

This invention relates to syringes of the character usually employed for internal bath, and conten'iplates the novel construetion and arrangement of parts wherein the syringe can be conveniently handled for the purpose intended.

More specifically stated. the syringe embodies a nozzle capable of being quickly and easily associated with a fluid supply tube or pipe, and equipped with a valve for regulating the flow of fluid through the nozzle as the occasion may require, the nozzle being sulriported on one end of a suitable handle so that the entire syringe can he conveniently handled or manipulated for the purpose desired. Y

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

ln the drawing forming part of this application, the like numerals or reference indicate similar parts in the several views, and wherein:

Figure 1 is a view in elevation showing how the syringe is associated for use with the fluid container.

Figure 2 is an enlarged fragmentary section al view through the syringe itself.

The syringe forming the subject matter of the present invention may of course be constructed of any suitable material, preferably of rubber, and may also vary in size and coniguratioi'i without departing from the spirit of the invention. The syringe however', embodies a nozzle indicated at 10, provided with a longitudinal bore 11 opening at both ends thereof as clearly illustrated in Figure 2. The nozzle 10 is provided with a reduced extension 11 at its lower end, terminating to provide an annular flange 12, so that when one end of a flexible hose 13 is slipped over the reduced extension 11, it will be held properly associated with the nozzle as clearly illustrated in Figure 1. This hose 13 may be connected with any suitable source of supply, preferably forming part of a hot water bottle or 'other container 14 adapted to be suspended from a wall or the like. The other end of 1927. Serial N0. 191,129.

the nozzle is reduced at 15, and is the end that is adapted to be inserted within an opening in the body, and is consequently rounded and smoothed to prevent injury to the latter. This nozzle is supported at one end of a handle 16 preferably formed as an integral part of the nozzle and arranged substantially at a right angle thereto. The handle may be of any desired length, but by reason of its arrangement and association with the nozzle, the entire syringe can be conveniently handled or manipulated for the purpose intended. The nozzle is also provided with a trans verse bore which intersects the bore 17, and arranged in the lirst mentioned bore is a retary plug valve 18 havingl a transverse port 19, adapted to register with the bore 17 when the valve is in its open position. The valve 18 is provided with a suitable handle 2() so that the valve can be conveniently opened or closed while the syringe is in use, 0r partly opened to regulate the flow of fluid through the nozzle.

lhile it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent. l desire to have it understood that l do not limit inyself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

lVhat I claim is A syringe for internal bath comprising a solid rubber body .including a relatively large intermediate portion and upper and lower reduced portions of considerable less diameter' than the intermediate portion, said body hav ing a longitudinal bore opening at both ends, a fluid supply pipe adapted to be associated with one of the reduced end portions, the other of said reduced end portions, and said intermediate portion having rounded or curved surfaces, a rotary plug valve arranged transversely of the intermediate portion and intersecting said bore, a handle for said valve arranged at one side of the body, and a handle for the syringe, said handle forming an integral part of the relatively large intermediate portion and arranged substantially at a right angle thereto.

In testimony whereof I ailix my signature.

JOHN WILLIAM ROIN'SON.
